HORSESHOE-MAGHINE.

Specification of Letters Patent No. 23,976, dated May 10, 1859.

To all whom it may concern:

Be it known that I, JOHN B. CoLLnN, of the city and county of Philadelphia and State of Pennsylvania, have invented 'certain new and useful Improvements in Horseshoe-ll Iachines; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing and to the letters of reference marked thereon.

My invention relates to horseshoe machines, in which a heated bar of iron is compressed to the desired form between dies; and my improvements consist, first, in bond ing a heated bar of iron to the requisite form, by applying it to a revolving former of the shape of the inside of the shoe, the

said former being arranged to hold the bent 11011, while it is acted upon by the dles, as. Second, 1n the combr.

set forth hereafter. nation of the revolving former with a knife, arranged substantially as hereinafter described, for the purpose of severing the bent end from the body of the heated bar. Thirdly, in a combination of a die, a spindle, with a former attached to the same, a sleeve, and a counter die, the whole being arranged in the manner fully described hereafter, and operating so as to compress the bent bar into the form of a shoe and allow the shoe to drop to the ground after being formed.

In order to enable others to make and use my invention, I will now proceed to describe its construction and operation.

On reference to the accompanying drawing, which forms a part of this specification, Figure 1, is a plan view, illustrating my improvements in horse shoe machines. Figs. 2 and 3, face views of the revolving dies, in different positions. Figs. 4 and 5, detached, sectional views of the dies, showing them at the limit of their outward movement. Fig. 6, the same, as seen when closed. Fig. 7 a modified form of dies.

Similar letters refer to similar parts throughout the several views.

A is the foundation of the machine, B the site side of the standard, being secured to the same sleeve. The wheel G gears into a spur wheel J, on a shaft which turns in standards E and H, secured to the base A, the shaft having a crank wheel I, which will be more especially alluded to hereafter. In standards L and M, secured to the base A, turns the hollow journal a of the die N, on which, and between the standards, is a pinion- 0, gearing into the segmental wheel P on the main driving shaft B.

In the interior of the journal 1%, and passing through the same, is a spindle Q, on the end of which is the former g. This spindle Q can slide longitudinally in the journal n to a limited extent, and its position is con.-

trolled by an arm R (Fig. 1), hung to a bracket on the standard D, and which may either be operated by hand, or by any mechanism so connected with the machine as to move at the time required. The spindle n with its former is also allowed to slide in its journals and in the hub of its pinion O, to a limited extent, and is moved forward at a certain point in the operation of the machine, by a projection 1" on the above mentioned arm R.

The die N on the hollow spindle n fits into a sleeve S, which is so arranged as to revolve with the die, the spindle Q and wheel 0. The sleeve, however, has a projection s, overlapped by strips't, secured to the side of the standard L, so that, although it is capable of revolving freely, it is maintained later ally invariably in the same position.

The sleeve S is of such a form, that on the inside it presents the shape of the outside edge of the horseshoe, and the former g presents the shape of the inside of the shoe, as bestobserved on reference to Figs. 2 and 3.

T is the counter die, of such a form as to fit freely but snugly into the sleeve S. This counter die is attached to or forms a part of the hollow spindle t, which turns in a standard V attached to the base A. A spindle it passes through the hollow spindle t, and the two are so secured together, that the spindle t with its counter die T shall revolve. freely, independent of the spindle a, and both slide together longitudinally. On the hollow spindle t is secured a pinion O, which gears into a segmental wheel P on the shaft B. The face of the counter die T is recessed, so as to receive the end of the former g and the end of the spindle Q.

In the die N are two recesses for containing the punches at, the latter being so constructed as to form the nail holes and re cesses on the underside of the shoe. These punches are connected by strips 29 (Figs. 2 and 3) to the sleeve S, so as to move with the latter.

The spindle u is connected to one end of the arm V of a toggle joint, the other arm V of the latter being connected to a stud 'w on the standard X, which is secured to the base A. Both arms of the toggle joint are connected to one end of a rod Y, the opposite end being connected to the pin of the crank wheel I. A knife :22 is secured to a bar 2 which is arranged to slidein the standards L and M, the end of the rod being loosely connected to the arm R.

The machine is set in motion by turning the pulleys C and F alternately. This is done by a strap, which admits of being readily transferred from one pulley to the other. WVhen the pulley F is turned, a rotary motion will be communicated, through the pinion Gr and wheel J, to the crank wheel, which, operating through the rod Y on the toggle joint composed of the rods V and V, will impart a reciprocating motion to the spindle u, the hollow spindle t and its counter die T.

When the pulley C is turned, the segmental wheels P and P will, (during part of their revolution) gear into the pinions O and O, and be the means of turning the die N, its sleeve S and other connections, as well as the counter die T, one complete revolution.

The movement of the lever B will operate the spindle Q and its former g, as well as the spindle n and the die N, the position of the knife m on the bar y being also changed.

Although I have shown and described certain mechanical appliances for causing the above mevements, they form no especial part of my present invention. The moving parts of the machine may, in fact, be operated by any system of gearing, which the nature of the movements and experience in mechanical construction may suggest as the most advantageous.

Supposing the die IT and counter die T, the spindle Q and its former g, and the sleeve S to be in the position illustrated in Figs. 2, 4 and 5; that is, with the spindle Q and its former fitting into the recess of the counter die T, the face of the die N being level or flush with the edge of the sleeve S, and both the dies, the sleeve and the former in the horizontal position shown in Fig. 2. An attendant takes a heated bar of iron, places it 011 the top of the former g, with the end of the bar bearing against a lip e on the end of the sleeve S, a pin f serving to retain the end of the bar in its proper position (see Fig. 2). Both the dies with their appurtenances now revolve simultaneously, and, by the time they have arrived at the position shown in Fig. 3, the end of the heated bar will have been bent around the former. Prior to arriving at this point however, the knife w on the bar 3 has been moved forward to such a position that it presents its sharp edge at a point in the range of the revolving dies, so that, on the movement of the latter, the bar is severed, leaving a heated piece of iron lapped around the former q. The counter die T is now, by the action of the toggle joint or other suitable device, pushed forward, forcing the heated piece of iron against the die N, and moving the latter back to the position shown in Fig. 6, the counterdie entering the sleeve, and the iron being squeezed between the two dies, so as to reduce it to the desired thickness, while the former on the inside and the sleeve on the outside, prevent the iron from spreading and impart to it the desired form of the inner and outer edge of the shoe. As the iron is being thus forced into its desired shape, it comes in contact with the punches at, by which the nail holes and slits for receiving the heads of the nails are formed on the underside of the shoe. The latter being now completely formed, the counterdie recedes to its former position, the spindle Q with .its former g is withdrawn from the recess of the counterdie and so far into a corresponding recess in the die N, that the shoe is released from the former, and drops to the ground. By the time the dies have again arrived at the original position shown in Fig. 2, the spindle Q with its former has again entered the recess in the counterdie, and all is now in readiness for the application of another heated bar of iron.

In the modified arrangement shown in Fig. 7, the end of the spindle Q, as well as the former, is cut so as to be expanded. A conical projection h, on the end of the rod u, entering the end of the spindle Q, at the time when the iron is squeezed between the dies, is the means of causing this expansion of the spindle Q and its former q, and consequently, of forcing the heated iron against the inside of the sleeve S, thereby condensing the edges of the shoe, and obviating that ragged appearance common to shoes made in other machines.

I claim and desire to secure by Letters Patent,

' 1. Bending the heated bar of iron to the requisite form, by applying it to a revolving former, of the shape of the inside of the shoe, when the said former is arranged to hold the bent iron, while it is acted upon by the dies, as herein set forth.

2. The combination of the revolving former, g, with the cutter, :0, when the latter is so arranged in respect to the former, that the edge of the cutter shall coincide or nearly coincide with the circular path travand the sleeve S, in combination with the counter die T, on the spindle, u, when the whole of the parts are arranged in respect to 15 each other for joint action substantially as and for the purpose specified.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN B. COLLEN.
